A 91-year-old man has shot and wounded another man during an apparent robbery attempt outside a Detroit-area store.

Eastpointe police say the intended victim was leaving his vehicle Monday morning when he was approached by another man who was behaving in an erratic manner.

The 91-year-old told the second man that he had a concealed pistol license.

Sgt. Martin Campbell tells The Detroit News that the elderly man warned the second man “three or four times and even had the gun pointed at him … but the suspect kept coming and pointed an unknown object at the victim.”

The second man was shot in the neck. He has been hospitalized and is in police custody.
